A great source of panadaptor information, as well as excellent buffer
amplifiers, is at G4HUP.com.

That's just noise from the passband of AO-7 transponder. It's stronger
in three spots, one on the middle of the passband and two near the
edges. These spots are quite strong, in fact comparable to some of the
stations. If you look closely, you can also see that these spots get
frequency modulated with the strong transmissions.
This is one of those things that it's quite difficult to see on a
traditional receiver but it's quite apparent on an SDR waterfall.

Message-ID: <000001d12778$e08e0e60$a1aa2b20$@xxxxx.xxx>
All,
There are several users on this list who use Flex rigs, pre-6k series, for
satellite operations. There
is a problem with the Flex PowerSDR FM implementation because it lacks a way
to bypass the audio
filtering. (Fixed in SmartSDR.) The low frequency attenuation is good enough
to prevent using the
normal audio to decode DUV, but poor enough you can hear the DUV rumble, or
the PL tones on a normal
repeater. However, there is a way, suggested by Dave, W0DHB to make this
work for DUV telemetry.
Fortunately the PowerSDR I/Q output bypasses the filtering, and FoxTelem can
accept I/Q inputs.
(According to the Flex people, the convention for I/Q is reversed in
PowerSDR, but I have had no
problem interfacing it to FoxTelem.)
If your only interest is telemetry, there are alternate approaches which are
probably better. I wanted
to be able to copy telemetry, but also be able to communicate at the same
time. I will assume users
have already installed Virtual Audio Cables, know how to hook software
programs together, and are
familiar with FoxTelem. All have good documentation. Additionally, different
choices for sampling and
buffers may well work, as well as different procedures for tuning, but these
are what I am using
successfully.
In PowerSDR, go to VAC 1 and select 48k sampling, 1024 buffers. (Under
Primary Audio, I use my normal
192k sampling, 1024 buffers.) Check both boxes in the Direct I/Q box. The
VAC audio level control does
not have any effect on I/Q signal levels. Enable VAC 1.
In FoxTelem, select the correct cable to get the audio from PowerSDR, 48k
sampling, and tick I/Q and
low speed.
I use SatPC32 to drive the Flex VU-5K. Tweak the downlink to center up the
display, as you do for
ordinary voice. Start FoxTelem. You will see the characteristic AO-85
display in the lower FFT pane.
Do NOT use the Find Signal or Track Doppler, yet. Instead, click on the FFT
display to tune FoxTelem.
You should be rewarded with a nice eye pattern, and SNR of 5-10. If you have
a strong signal, select
the Track Doppler. It will hunt briefly, and then settle down to something
close to optimum.
Generally leaving Doppler Track checked is the most flexible since it will
adapt to the slight changes
in the downlink frequency. You may miss a few packets around AOS however. If
you uncheck it, the
"sweet spot" will not change since SatPC32 will keep it tracking, so long as
you adjust for the
current downlink frequency. I normally leave my checked.
This technique gives nearly 100% copy without compromising voice operations.
In principle it should
work for high speed telemetry, but to date I have not been successful.
Probably a sample rate/buffer
issue.

Alan

Ham Radio Travel day:
Don?t forget to monitor 144.39 with CTCSS 100 and get automatic alerts
(pings) when you are in mobile simplex range of another mobile traveler
(running APRS).
It works with ANY mobile radio. As long as you have CTCSS set to 100.
It is better than CQ 52 because the other mobiles are sending out a ping
once a minute instead of an occasional CQ call on 52. With cars passing
each other at a combined 120 MPH, you are only in range of each other for a
few minutes. So, you can either call CQ every 2 minutes all day long, or
you can sit back and monitor 144.39 with CTCSS 100 and let the radio do the
work.
For more info, see http://aprs.org/VoiceAlert3.html
Happy Travels.

Hi all and Happy Thanksgiving,
Question.. how many of you are doing SAT work with a
FLEX-6000 series rig? I'm in the processes of pursuing just that, got my
first Transverter to build, while I'm waiting figured I'd start the
conversation on how do you have everything setup? I had a 9100 and could do
full duplex and am wondering if the FLEX with transverters will allow the
same full duplex operation (I'm assuming it will)
Keep in mind here I am new to this transverter thing and have never set one
up before..
Thanks

I had both main and sub-band IF taps added to my Icom IC-910h. I wasn't
as impressed with it as I'd hoped. My recommendation for satellite
panadapter use is to setup relays between each band, your transmitter,
and your SDR.
In fact, I have a Clifton Labs buffer amp sitting my drawer. If someone
wants it, email me off-BB.

I think it is caused due the components age/conditions which is affecting
its receiver linearity, noticed even in a such narrow band.

It is a SNR (signal to noise ratio) matter, if you position your TX on the
top of the hill you can hear it stronger but the noise is also stronger, if
you slip to the mid of the valley your signal will be weaker but noise as
well. In a practical experiment (using my ears) I noticed a better SNR
relationship staying in between the valley and the hill, which will be very
difficult to find for who uses a regular rig for RX.

Content-Type: text/plain; charset="us-ascii"
I started working satellites in April of this year and have been using
Heavens Above to track ISS, SO-50 and AO-85. Because of my location (my
back yard) SO-50 has not been in a good position during the day for me to
work. I have been trying to work AO-85 but have not heard it for the past
week. I initially thought that the antenna had a problem but it wasn't
since I could hear conversations on various repeaters in the Phoenix AZ
area. This morning it downed on me to check AmsatDroid Free on my phone. I
found that the information on passes listed on Heavens Above was early, the
LOS time was actually the AOS time on AmstatDroid Free. I have been setting
up for a pass and getting on early using the Heavens Above information and
getting off just as AO-85 was reaching AOS. Up until this past week Heavens
Above has been very reliable. Both the Android phone version and the
internet software version are giving the same pass times. Using the pass
times from AmsatDroid Free I was able to hear conversations on AO-85 this
morning but was unable to make contact. That's me being new to AO-85 which,
I have read, can be frustrating.

Thanks,

Hi!
After seeing several people at my demonstration in Goodyear
AZ last week used their HTs with standard duckie antennas to
hear AO-85 as it passed by, and seeing many positive comments
on how easy it is to hear this downlink, I decided to try it
for myself. On my way to the office this morning, I stopped
at a shopping center parking lot for the AO-85 pass around
1438 UTC to hear this pass. AO-85 went up to a maximum
elevation of 41 degrees, which would have been a nice pass
to work if I had my Elk log periodic in the car.
After about 3 minutes into the pass, I could hear the round-
table conversation taking place. Using my Wouxun KG-UV9D HT
and a Nagoya NA-701 2m/70cm duckie antenna that is about 8.5
inches/22cm long, and with the squelch open, I was able to
listen to the downlink. I had to move the HT around while
listening to the downlink, but I was hearing it. I had the
HT in narrow FM, as I described in my report on working
stations via AO-85 using this HT and my Elk log periodic
antenna I sent to the -BB yesterday. I had to adjust the
frequency down from 145.980 MHz through 145.9775 MHz to
145.975 MHz near the end of the pass, using one of the
HT's VFOs.
While I was listening to this pass, I used my mobile phone
to make a short video clip of what I was doing. The 4-minute
clip I recorded around the middle of the pass is now on
YouTube at:
https://www.youtube.com/watch?v=OZDpRZHd2FE
There is a point in this video clip where I was not hearing
the downlink, as I dropped the radio into my car. Once I
picked it up and held it outside the car again, I was able
to continue hearing the downlink. This is not a professional-
grade video (it was recorded in 720p, but I'm not a movie
producer), but it shows that we don't need much to hear AO-85.
During this pass, I heard several stations, and the video
clip has most of them. I was hearing WA6DIR in California,
KC7MG in Arizona, AA5PK in Texas, W7SXM in Washington state,
and late in the pass I heard KC9ELU in Indiana. If I had
planned this out better, I would have tried to record more
of the pass, and made sure I didn't drop the radio during
the recording.
Happy Thanksgiving, and 73!
